Abstract
Disclosed is a method for manufacturing a functionalized separator having a zwitterionic coating thereon. The method includes preparing a porous separator; coating a linker on a surface of the porous separator; and chemically reacting zwitterions with the linker such the zwitterions are grafted to the linker on the surface of the separator. The zwitterions grafted to the linker acts as a monolayer to functionalize the surface of the separator. The functionalized separator may disallow elution of polysulfide compound in a lithium-sulfur battery. Further, the functionalized separator may increase ion conductivity of electrolyte of the lithium-sulfur battery and thus ensure high output characteristics.
